  • the UART communication is improved based on UART Idle line detection interrupt
  • an Rx ring buffer is used to manage the UART incoming data
  • both Tx and Rx are efficiently handled using DMA
  • added posibility for User commnds via UART in DEBUG mode
  • added platformio.ini so firmware can be built using Platformio too
